CLOSURE CAP.

Application filed February 26,1924. Serial No. 695,388.

To all whom it may concern:

Be it known that I, PHILIP GASSETTA, a subject of the King of Italy, andresident of Paterson, county of Passaic, and State of New Jersey, haveinvented certain new and useful Improvements in Closure Caps, of whichthe following is a specification.

My invention relates to closure caps of the type commonly referred to asbottle caps and which generally speaking are crimped upon the bottle orother receptacle. In removing such caps from the bottle or otherreceptacle it is necessary to make use of an implement commonly termedan opener. The particular object of the present invention is to providea cap of the indicated character'with a device whereby said cap may bereadily removed from the bottle or other container without requiring.the use of such opener or any other extraneous tool or implement. Othermore specific objects will appear from the description hereinafter, andthe features of novelty will be pointed out in the claims.

In the accompanying drawing which illustrates an example of theinvention without defining its limits, Fig. 1 is a plan view of theimproved cap; Fig. 2 is a side view thereof showing the same in positionupon the neck of a bottle; Fig. 3 is an enlarged cross-section on theline 3-3 of Fig. 1 andv Fig. 4 is a detail view of the device forremoving said cap.

As shown in the drawings the cap itself may be of any customary and wellknown construction and includes a top 5 and the flange 6, crimped at 7upon the bottle orother receptacle 8 in any well known way. The top 5 ofthe cap is provided with a slot 9 which extends outwardly along a radiusof the cap and terminates at an annular bead 10 struck up from said topas shown in Figs. 1 and 2. The bead 10 is thus interrupted inregistrywith the slot 9 to provide oppositely disposed bearings 10 adapted toaccommodate the trunnions 11 of a lever 12 which constitutes the capremoving device. The lever is bent as indicated at 13 to provide afulcrum section and normally extends over the peripheral edge of the capand depends therefrom along the receptacle 8 as shown in Fig. '2. A discis located interiorly of the cap in surface engagement with the topthereof and bridges the slot 9 as illustrated in Fig. 3. The discreferred to may comprise the customary packing 14 usually found in capsof the indicated type, or it may be a metallic plate 15 combined withsaid packing and shaped to fit the interior of the cap as shown in Fig.3.

The cap is applied to the bottle or other receptacle 8 in the usual way,either by hand or by suitable machinery; in the latter case the bead 10receives the thrust of the capping machine and distributes the sameuniformly over said cap so that the latter is evenly applied to thebottle or other receptacle which it is intended to close; at the sametime the annular bead neutralizes the crushing force of said mechanismand prevents the same from injuring or destroying the bearings 10".

When it is desired to remove the cap the I lever 12 is pivotally movedfrom the posi-. tion indicated by solid lines in Fig. 3 to the dottedline position therein in which said lever extends upwardly from the capready for use in prying the latter loose from the bottle or otherreceptacle 8. That is to say the lever 12 when brought to the dottedline position in Fig. 3 shifts the fulcrum section 13 into engagementwith that part of the disc 15 or its equivalent, which lies in registrywith the slot 9 and thereby becomes a lever of the first class. If thelever 12, when in the dotted line position, is forced in the directionof the arrow in Fig. 3 it will fulcrum upon the section 13 and disc 15or its equivalent and accordingly exert a lifting leverage upon thepivotal connection or specifically upon the bearings 10 through themedium of the trunnions 11. In this way the cap is easily removed fromthe bottle 8 or other receptacle by means of said lever and withoutrequiring the use of any other tool or implement.

In its normal position the lever 12 occupies an inconspicuous positionadjacent to the bottle or other receptacle 8, in which it does notinterfere with the normal'handling of the bottle or with the placingthereof in boxes or other carriers. The annular head 10 and thoseportions of the lever which normally are in a position above the cap,present' no interference to the manipulation of a bottle or othercontainer 8 in any conventional manner. The device is simple inconstruction and eflicient in operation and being connected with the capis always L 15 or its equivalent available for use when required. Theslot 9 in addition to its other functions permits the trunnions 11 to beeasily inserted into the bearings 10*; this may be readily accomplishedby placing the trunnions lengthwise insaid slot and then by a quarterturn of the lever 12 passing them beneath and into the bearings 10 Whilethe device is primarily intended for use in connection with bottle capsit is obviously capable of incorporation in caps intended as closuresfor other receptacles.

In the preferred procedure the cap is applied to the bottle in thecustomary manner and t-he lever 12 is combined therewith, in

the'manner previously set forth, after the cap is in position on saidbottle. The arrangement is always such, thatthe fulcrum section 13of'the lever 12 bears upon that part of the disc 15 or its equivalentwhich the bottle neck.

The latter thus acts to resist the forceexerted upon said fulcrumsection 13, in the act of removing the cap, and thereby prevents theinward deformation of the disc and at the same time provides afirmfoundationfor the fulcrum of the lever:

Various changes in the specific form shown andv described may be madewithin the scope of the from the spirit of I claim: I H I 1 k 1.
